The objective of the research project was to develop a new guardrail system for box culverts capable of unsupported spans on the order 7.62 m. The new guardrail system was designed to meet the Test Level 3 (TL-3) safety performance criteria set forth in the NCHRP Report No. 350, Recommended Procedures for the Safety Performance Evaluation of Highway Features (2). First, a literature review was performed on existing long-span guardrail systems as well as guardrail systems attached to culverts. Second, a concept development phase was performed to identify several prototype configurations to be further analyzed and evaluated. Third, computer simulation modeling was conducted to aid in the analysis, design, and evaluation of several long-span guardrail configurations. Fourth, full-scale vehicle crash tests were performed using 3/4-ton pickup trucks, weighing approximately 2,000 kg, with target impact speeds and angles of 100.0 km/hr and 25 degrees, respectively. Finally, the test results were analyzed, evaluated, and documented. Conclusions and recommendations were then made that pertain to the safety performance of the new long-span guardrail system.
